Hi all,
I try to make a 3 tier application
i have a Bussiness Logic Serializable() class Art which have method public dsArt GetData();
i have an Interface IClient with method dsArt GetArtData();
I have a class public class ServerAdmin : MarshalByRefObject, IClient with method
public dsArt GetArtData()
{
BLL.Art obj = new Art(); - this is Bussiness Logic class
return obj.GetData();
}
in server application i do:
BinaryServerFormatterSinkProvider providerServer = new BinaryServerFormatterSinkProvider();
providerServer.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;
BinaryClientFormatterSinkProvider providerClient = new BinaryClientFormatterSinkProvider();
IDictionary props = new Hashtable();
props["port"] = 9000;
props["name"] = "ServerChannel";
TcpChannel chan = new TcpChannel(props, providerClient, providerServer);
ChannelServices.RegisterChannel( chan );
RemotingConfiguration.ApplicationName = "ServerObject";
RemotingConfiguration.RegisterWellKnownServiceType(
Type.GetType( "Server.ServerAdmin, Server.ServerAdmin" ),"Server.ServerAdmin.Binary", WellKnownObjectMode.Singleton );
In client I do :
BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
serverProvider.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;
IDictionary props = new Hashtable();
props["port"] = 0;
props["name"] = logid;
props["typeFilterLevel"] = TypeFilterLevel.Full;
TcpChannel chan = new TcpChannel(
props,clientProvider,serverProvider);
private IClient adminServer = null;
adminServer = (IClient ) Activator.GetObject(
typeof( Interfaces.IClient.IClient ),
GetHost() + GetPort() + "/" + GetURL());
and everythins work good
unless :-)
returned dataset contains 1.000.000 rows
the dataset contains only one table filled with Select *
i recieve an error message:
"System.ArgumentOutOfRangeException: capacity must be greater than zero.\r\n
Parameter name: capacity\r\n\n

Does anyone have a solution to problem ?
thanks in advance !
sorry for possibly language errors :-)
